treatment. A review of 20 cases. Goossens M. De Stoop N. Clinical Orthopaedics & Related Research. 176):154-62, 1983 Jun. Tarsometatarsal fracture-dislocation is an uncommon but severe lesion. Since this diagnosis is over-looked in about 20% of cases, accurate radiographic examination is imperative. In the presence of suggestive clinical signs and negative standard roentgenograms, stress-films in eversion-pronation and inversion-supination are obtained under general anaesthesia. A review of 20 cases shows that plaster cast immobilization without reduction is unsatisfactory, often resulting in Sudeck's atrophy and subsequent painful degenerative arthritis. Secondary fusion may be necessary to relieve symptoms. The treatment of choice is anatomic reduction and transfixation with Kirschner wires. The major complication is arterial damage with necrosis of the forefoot. Amputation may be necessary.
